Related, in the sense that ambient affects the battery temperature. Your link mentions that the throttling occurred at the second DCFC, but the important detail is that the first DCFC was a short one. Does that mean that summer range is initial SoC + a little more ? Without more battery temperature data we don't know more about the trigger(s). With summer upon us reports should come in a flood, but this all sounds like somewhere between bad and really bad, both for the effect on longer trip driving and the implications it has for battery degradation.

For all 2018 Leaf owners or possible future owners who are planning for long trips and want definitive information about what happens with heat and charge throttling, check out this new article on Cleantechnica:

Other than the performance of quick charging, we have zero data on degradation. That is the bigger question IMO, at least for me. Of course I live in the Midwest and don't see any EV other than a Tesla having real road trip potential currently.

To be clear, world-wide there are no issues that have been discovered with the 2018 battery.

What has been discovered is that 97% of those that have a 2018 don't have a driving regime that requires multiple daily quick charges, and those that do, are able to complete their quick charge successfully.

The safety and longevity safeguards built into the LEAF operate as designed using the same method that ALL other BEVs quick charge systems employ, namely the throttling of the charge level to mitigate heat degradation. The result of that is that it may take a little longer to complete a quick charge session. It does not matter if you quick charge a LEAF, Bolt, Tesla or VW, all of these BEVs employ throttling of the charge to promote battery longevity, which will vary the time that a quick charge session lasts. Depending on the variables that occurs during your Quick Charge session "Your quick charge session time may vary."

Some find that intolerable, but then again, if there weren't safety systems to protect the longevity of the battery, those same outraged complainers would find that intolerable as well.
